Interesting service bulletin about body sway in early models due to only having a few leaves in the rear springs.

My 92 chassis indeed only has three leaves in the rear. Thinking of replacing with the later nine leaf version.

That's an interesting find. Kinda makes a person wonder how many TSB's are out that that one hasn't read yet :?

Just out of curiosity I looked at a photo I'd taken that included my rear leaf springs (I know my year is well after those included in the TSB, but after reading it I was curious). Mine does have the 9-leaf springs that are cited as the remedial "action" in the TSB.

I see they say your year could have either 3-, 4-, or 5-leaf springs. Since you only have the 3-leafers it seems you'd experience a noticeable difference with the 9-ers. (Or go for broke and get the parabolic springs :twisted: )

Durn.

If the original owner had the Bumper-to-bumper warranty, it would've been covered for free if they'd taken it in :lol:

I'm torn between adding a spring helper, getting a spring shop to add a few more leaves, replacing with the later nine-pack, or using a sway bar instead.

Meh. It doesn't really sway enough to force me to do anything, so any change would be more like icing on the cake for me :D
